Let me know when Strava, Training Peaks, TrainerRoad or my Garmin watch etc, show HR or Power Levels in the 3 Zone Model.
After reading the pro/elite thread with hundreds of files of pro cyclist, I don’t buy the 80/20 thing any more. Those guys and gals spend WAY too much time in the “grey zone” doing a bunch of stuff throughout their workouts. They don’t do 4 easy rides at 68% then bury themselves with Wynne -4 or Spanish Needle the other 2 days. Plus, as is pointed out often, all this POL talk is descriptive not prescriptive.
The retroactive studies rarely have majority cyclists, meh.
